Fairy Philosophy

The Fairy Philosophy (妖精哲学, Yousei Tetsugaku), the Three Major Principles of the Big Brother, or simply "Philosophy" (哲学, Tetsugaku) is a set of three principles influenced by mishearings of Billy Herrington's dialogue with other wrestlers, resulting in Billy being viewed as a philosopher in Gachimuchi fanon. They are referenced in many Gachimuchi videos.

"Forest Fairy" (森の妖精, mori no yousei) and "Philosophy" (哲学, tetsugaku) were deliberately misleading tags used at Nico Nico Douga for Gachimuchi wrestling videos. The nickname "Forest Fairy" (also a Japanese slang term for a homosexual person) was derived from a scene in which Billy Herrington appears as a fairy coming out of a forest.

A poster of the Three Major Principles appeared in an episode of the Japanese animated series, "Plastic Memories". It can be seen on the right side of the picture (right), behind the man wearing a blue shirt.
